Astronomy Picture of the Day

   [1]Discover the cosmos! Each day a different image or photograph of our
      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

   Explanation: The Mars InSight lander returned its [6]first image from
   the Red Planet's flat, equatorial [7]Elysium Planitia after a
   successful touchdown on November 26, 2018. The history making mission
   to explore the martian [8]Interior using Seismic investigations,
   geodesy, and heat transport has been operating for over 1,400 martian
   days or sols. In that time the InSight mission has detected more than
   1,300 marsquakes and recorded data from [9]Mars-shaking meteoroid
   impacts, observing how the seismic waves travel to provide a glimpse
   inside Mars. Analyzing the archive of data collected is expected [10]to
   yield discoveries for decades. But InSight's final operational sol is
   likely not far off. [11]The reason is evident in this [12]selfie
   recorded earlier this year showing its deck and large, 2-meter-wide
   solar panels covered with dust. Kicked up by martian winds the dust
   continues to accumulate and drastically reduce the power that can be
   generated by InSight's solar panels.
